Recommended Sidewall Insulation Retrofit for Poultry Buildings

Poultry Houses in the US were originally designed to feature open side walls to assist with ventilation during warmer months. Recently, the design has evolved to closed side walls to assist in back-pressure ventilation.

The poultry houses with closed sidewalls typically featured blown fiberglass or batting inside the walls for insulation and a thin plastic membrane to seal up the wall.

This integration of one thin layer of plastic vapor barrier and fiberglass insulation in sidewalls of a poultry house was originally used by integrators because it was the cheapest way to insulate sidewalls.

Unfortunately for Poultry Farmers, this integration of materials is temporary at best, and has added tremendous cost and hardships for Poultry Farmers. The failure of this integration in Poultry Houses has been quite high.

The single layer of plastic vapor barrier develops holes, creating challenges to maintain back-pressure.

The Fiberglass in the sidewalls is quite frail and either settles to the bottom of the wall, gets damaged by moisture, or destroyed by Darkling Beetles.

The results of the failed integration are high fuel costs and the farmer having to replace his sidewall insulation at his great expense.


Apply two layers of Polyshield Double Bubble Lifetime Guaranteed Insulation in the sidewalls of your Poultry House.


Simply remove your metal sidewalls and remove the existing insulation.

Apply our double-sided tape to the middle of the inside surface of your wood beams so that when you push the first layer of Polyshield Bubble insulation in between, the tape grips the bubble and creates a seal. You then add a staple every couple of feet to permanently attach the bubble to the wood surfaces. You tape the Bubble Insulation to the top of the wall and the bottom of the wall with our foil tape to seal the bubble.

Secondly, you wrap the outside of the wood wall with a second layer of Bubble Insulation, taping all the seams, and taping the bubble to the top and bottom of the wall to finish the seam.

Re-attach the metal wall to the outside wall using traditional install methods.


This install method provides 4 layers of plastic vapor barrier, R-20 in a 4” wall cavity, and 95% Reflectivity that improves the Thermal Resistance of the Sidewall by 50%. Most importantly, Polyshield Double Bubble Insulation has a lifetime warranty against failure.

This install method has been successfully applied in different regions in the US and many times over the last few years has been funded through the NRCS EQUIP program.
